Nothing
The etm (empirical transition matrix) package permits to estimate the matrix of transition probabilities for any timeinhomogeneous multistate model with finite state space using the AalenJohansen estimator. Functions for data preparation and for displaying are also included (Allignol et al., 2011 <doi:10.18637/jss.v038.i04>). Functionals of the AalenJohansen estimator, e.g., excess lengthofstay in an intermediate state, can also be computed (Allignol et al. 2011 <doi:10.1007/s001800100200x>).
